Title:
アルミニウム合金板の重ね隅肉溶接方法
Document Type and Number:
Japanese Patent JP7132830
Kind Code:
B2
Abstract:
To provide a fillet welding method for an aluminium alloy plate in which occurrence of cracking can be prevented.SOLUTION: An irradiation period S1 during which a laser beam Q is radiated and an interruption period S2 during which the irradiation is interrupted are alternately repeated while making a galvano-scanner 20 move a position Qf to be irradiated with the laser beam Q along a welding line G. In the irradiation period S1, the position is scanned for a length of 35 mm or less along the welding line G to form a weld bead. In the interruption period S2, the irradiation of the laser beam Q is interrupted for time corresponding to one third of the irradiation period S1.SELECTED DRAWING: Figure 1
